STEM WINDING AND SETTING AUTOMOBILE CLOCK.

v Application filed February 13, 1923.

To all fio/tom t may concern.'

Be it known that I, WILSON E. PORTER, a citizen of the United States,residing at New Haven, in the county of New Haven and State ofConnecticut, have invented a new and useful Improvement in Stem vWindingand Setting Automobile Clocks; and I do hereby declare the following,when taken in connection with the accompanying drawings and thecharacters of reference marked thereon, to be a full, clear, and eX- actdescription of the saine, and which said drawings constitute part ofthis application, and represent, in-

Fig. 1 a view in front elevation of a stem winding and settingautomobile clock constructed in accorda-nce with my invention.

Fig. 2 an enlarged broken view thereof, with the bezel, dial and handsremoved.

Fig. 3 a view thereof, partly in side elevation but mainly in verticalcentral section.

Fig. 4 a reverse plan view of the movenient thereorn as removed from itscase.

F 5 astill further enlarged detail seeticnal view of the upper end ofthe winding and setting stem, with the wheels carried by it.

lily invention relates to an improvement in stein winding and settingautomobile clocks, the object being to provide a simple, compact andreliable time-piece of the character described, constructed withparticular reference to ruggedness and durability of construction andease of operation, and adaptability to cowls of widely varyingthickness.

lith these ends in view, my invention consists in a stem winding andsetting automobile clock having certain details of construction andcombinations of parts as will be hereinafter described and particularlypointed out in the claims.

As herein shown, my invention is applied to an eight-day clock-movementhaving a main winding-wheel 10 located against the back of the rearmovement-plate 11 and meshed into by a relatively small winding pinion12 mounted upon the rear end of a winding-arbor 13 bearing in andprojecting rearwardly through the said plate 11 Serial N0. 618,782.

and having bearing at its forward end in the front movement-plate 14. Atits forward end, the said arbor 13 carries a drivenwheel 15 locateddirectly back of the plate 14 and constantly in mesh with a windingwheel16 loosely mounted upon the projecting upper end of a winding andsetting stem 17 located within a bearing-tube 1S secured by its upperend to the cup-like clock-case 19 well back from the front thereof. Thesaid stem 17, which has limited longitudinal as well as rotary movementin the tube 18, is furnished at its lower end with a winding and settingbutton 20. Upon its upper face, the said winding-wheel 16 is providedwith face ratchetteeth 21 normally meshed into by corresponding faceratchet-teeth 22 upon the lower face of a setting-wheel 23' staked uponthe extreme upper end of the stem 17. Normally, the stem 17 is coupledthrough the face ratchet-teeth 21 and 22 with the stem 17, so that theclock is normally ready for Winding, which is rendered very easy by thesmall size of the pinion 12 relative to the size of the mainwindingwheel 10.

The stem setting-wheel 23 aforesaid is constantly in mesh with asetting-wheel 24 mounted upon a large sleeve-like or hollow stud 25staked into a yoke 26 and large enough in diameter not only for thepassage through it of the reduced forward end of the winding-arbor 13but also to permit the swinging movement of the yoke with respect to thesaid arbor'. The said yoke is hung upon a stud 27 mounted in the forwardface of an intermediate movementplate 28, which is formed in its loweredge with a clearance-opening 29 for the clearance of the winding-arbor13 and the fianged inner end of the tubular stud 25 carrying thesetting-wheel 24, which is located upon the forward face of the yoke.

The setting-wheel 24 meshes into a pinion 30 turning upon a stud 31 inthe outer end of the yoke, the outer end of the said stud having anextension 32 for engagement by the free end of a yoke-spring 33 coiledupon the adjacent movement-pillar 34 and having its inner end 35 hookedover the edge of the front movement-plate 14. The said yoke-springexerts a constant eiort through the yoke 26 to maintain the mechanism inreadiness Jior winding by keeping the face ratchet-teeth 21 and 22 inengagement, at which time the winding and setting stem 17 is in itsdepressed position.

Vhen the stem 17 is lifted or pushed inward against the tension of theyokespring 33, the yoke 25 is rocked upon its stud 27 and theyoke-pinion 30 brought into mesh with an inner intermediate settingwheel36 located at the inner end ot a sleeve 37 turning loosely upon a stud38 mounted in the intermediate movement-plate 23, the outer end of thesleeve 37 carrying an outer intermediate setting-wheel 39 located justin front of the front movement-plate and meshing into the dial orminute-,wheel -i-O et the dial-work, of which only the pinion 41 and thehour or socket-wheel e2 are shown. For the easy assembling ot theintermediate wheels 36 and 39, and the sleeve 37, on which they aremounted, the :tront movement-plate 14 is formed with a clearance-opening43.

rl`he yoke-spring 33 maintains the mechanism normally in readiness forwinding, as described. To set the clock, the stem 17 is pushed inwardagainst the tension of the yoke-spring 33, whereby the upper tace of thewheel Q3, by engaging with the edge of the yoke 26, swings the same uponits stud 27, whereby the yoke-pinion 30 is brought into mesh with theinner intermediate settingwheel 36 at the inner end or" the sleeve 37,the outer end of which carries the outer intermediate setting-wheel 39,which is in constant mesh with the minute or dial-wheel l() of thedial-work. At the same time, the ratchet-teeth 21 are disengaged fromthe ratchet-teeth 22, thus cutting the windingtrain out of action.Inward pressure upon the stem 17 being maintained, the clock is set byturning the same in one direction or the other as required. The instantinward pressure is removed from the stem 17, the yoke-spring 23 assertsitself to restore the parts to their normal positions of readiness forwinding.

By employing a winding-arbor extending between the front and rearmovement-plates and by passing the same through ayoke positioned betweenthe said plates, I am enabled to locate the winding and setting stem 17and its tube 18 suliiciently to the rear of the front of the clock-ease19 to adapt the same for use with cowl boards of a wide range ofthickness.

I claim:

1. In a stem winding and setting clock, the combination with thewinding-arbor thereof, of a stem winding and setting mechanism,comprising an oscillating yoke, a hollow stud carried thereby, asetting-wheel turning loosely upon the said stud, and a setting pinionalso carried by the yoke and meshed into by the said setting-wheel, thesaid hollow stud being large enough for the said winding-arbor to passthrough it with sufficient play for the oscillation of the yoke.

2. In a stem winding and setting automobile clock, the combination withthe case thereof, of a bearing-tube secured in radial relation theretoabout midway the depth of the case from Jfront to rear, a winding andsetting stem having bearing in the said tube and provided at its upperend with a loose winding-wheel and a fixed settingwheel, means forconnecting and disconnecting the said wheels by the longitudinalmovement of the stem, a clock-movement located within the said case andhaving its winding and setting trains positioned for coaction with thesaid winding and setting wheels upon the said stem.

3. In a stem winding and setting autoincbile clock, the combination withthe case thereof, of a radial bearing-tube depending 'from the caseabout midway the depth thereof, a winding and setting stem havingbearing in the said tube and mounting a lined setting-wheel and a loosewinding-wheel, a clock-movement located within the said case and havingfront, rear and intermediate movement-plates, a winding-arbor mounted inthe said front and rear movement-plates, and winding .and settingtrains, including an oscillating yol'e mounting a setting-wheel and asetting-pinion through the 'former of which the winding-arbor passeswithout interfering with the oscillation ci the yoke, which is shiftedby the inward movement of' the stem to bring its setting-pinion intomesh with a wheel of the said setting-train.

In testimony whereof, I have signed this speciiication in the presenceof two subscribing witnesses.
